ActiLife can automatically create *.csv files on download by setting this in the edit menu. Note

that this only works for GT3X+ devices if an *.agd file is created during the download process.

Downloading GT3X+ Devices

Downloading data from GT3X+ devices is very similar to download from other devices. It is important to understand the

difference in the file handling for this device. In order to increase the efficiency of the download process, data from

GT3X+ devices is downloaded in raw, binary format with file extension *.gt3x (see

Appendix A – File Types in ActiLife5

explaining the *.gt3x format). This binary format mirrors the proprietary compressed raw data format stored on the

device itself and is unreadable by standard text editors. These files (*.gt3x) are in a maximum compression format and

are optimal for emailing or FTP file sharing with colleagues. In order to read the data or process the data with ActiLife,

the *.gt3x files need to be uncompressed (i.e., exported to *.agd format) using ActiLife. This can occur either during

download or later when processing files.

To download data from a GT3X+, select the device(s) from the grid in the Devices tab and click “Download”. A prompt

similar to Figure 29 will appear. Clicking “Download All Devices” will immediately download all of the data from the

GT3X+ into the user’s default download directory.

Scanning of GT3X+ Data during Download

Data downloaded from GT3X+ devices can be scanned for problems at the time of download. At this time, ActiLife can

scan for null data (0s) which may indicate issues with the device accelerometer or non-compliance by the end-user. To

enable this scanning, open the Edit->Options menu and choose the Downloading submenu. In the “Scan of GT3X+

Download” section, select the warning threshold. Doing so will warn the user during the download process if the

number of 0s within the file exceed the threshold. To disable this feature, set the threshold to 100%.
